l an abutment for the doors 10 when the same are in closed position. rlhe flange 12 of the angle member is equipped with a forwardly projecting striking plate 1st. @ne flange 15 of another angle member is secured to thel lower ends of the side bars 2, the other flange 1G of the angle member constituting an abutment for the lower ends of the doors 10. The flange 15 is provided with an outstanding striking plate 17 projecting through communicating notches 18 in the lower portions of the meeting edges of the doors 10. litt this point it may be noted that the flange 15 constitutes a closure for the notches 18. lf desired, the doors 10 may be peripherally bound as indicated at 19.

rThe inner ends of the hinge members 8 terminate in guides Q0. llhese guides 2O overlap the inner ends of the hinge meinbcrs 9 and, in combination with the locking mechanism hereinafter described, constitute means for holding the doors in closed position. Mountedto slide in the guides Z0 of the hinge members 8 are locking bolts denoted by the numerals 21 and 22. The upper locking bolt 21 is adapted to engage with the striking plate 14 and the lower locking bolt 22 is adapted to engage with the striking plate 1T. Secured to one of the doors 10 adjacent the free edge thereof is a wear plate 9.3 to which a reversely curved lever Q-l is united intermediate its ends, by a primary pivot element By means of secondary pivot elements 26, the adjacent ends of the locking bolts 21 and 22 are pivotally connected with the lever 24 upon opposite sides of the pivotal connec tion 2 5 upon which the lever Q4: swings. The adjacent ends of the locking bolts Q1 and 22 are curved in opposite directions to define concaved seats 27 in the inner edges of the locking bolts. Adjacent its ends, the lever 24:' is equipped with projections in the form of bosses or studs 28.

Referring particularly to the locking mechanism, it will be understood, noting particularly Fig. 5, that the lever 211 may be swung upon its pivotal mounting 25 so as to advance the locking bolts 22 and 21 in opposite directions, so that the locking bolt 22 will engage with the striking plate 17, the locking bolt 21 engaging with the striking plate 14. When the parts are thus posi- To all whom it may concern lle it known that I, Josinrr MGCOLLY, a citizen of the United States, residing at lllavne, in the county of El Paso and State of Colorado, am administrator of the estate of Grunt-ns C. McCoLLr, deceased, late of llVa-yne, in the county of El Paso and State of Colorado, who in his lifetime invented a new and useful Bolting ltllcchanism, of which the following is a specification.

Une object of the present invention is to provide nov..L means for locking the doors of a combined end gate and shoveling board.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

in the drawings, Figure 1 shows the invention in elevation; Fig. 2 is a longitudinal section; Fig. 3 is a transverse section; Fig. l is an elevation showing the locking boltsin unlocked position; Fig. 5 is a detail enlarged from Fie. 1; and Fig. 6 is a detail perspective of the lower striking plate and adjacent mechanism.

In the drawings there is ing structure comprising a top plate 1 and spaced side'bars 2. Angle members 3 are provided, certain flanges d of which overlap. the forward faces of the top plate 1 and of the side bars 2, the angle members 3 constituting means for holding the top plate and the side bars together. rlhe other flanges 5 of the angle members 3 project forwardly and constitute the side walls of the combined end gate and shoveling board. rlhe drawings show angular hinge members G, the members G being secured to the flanges 4l and 5 of the angle members 3, the hinge members 6 serving as reinforcing elements for the flanges 5 which constitute the side walls of the shoveling board. rlfhe hinge members are knuclrlcd as indicated at 7 upon other hinge members 8 and 9, the hinge members 8 and 9 being connected with. doors 10. One flange 12 of an angle member is secured to the lower edge of the top plate 1, the other flange 11 thereof constituting shown a supportf bolts, in a direction tioned, the bosses 28 will engage in the coniconstruction, therefore is such that when the' parts are positioned as shown in Fig. 5, the locking bolts 2l and 22 cannot become disengaged with their respective striking plates, saving by manual manipulation ot' the lever 2l-. The locking bolts 2l and 22 are thus held positively in engagement with the respective striking plates and no matter how strong a thrust is applied to the locking parallel to the long dimension of the lever, the locking bolts cannot thereby become disengaged from the striking plates. lt will be understood readily, that the locking bolts 2l and 22 may be disengaged respectively, from the striking plates 14 and 17, by swinging the lever 2a into the position shown in Fig. et. It is to be observed that the adjacent ends of the locking bolts 2l and 22 are curved in opposite directions, and that the lever 24 is reversely curved. Owing to this construction, it will be exceedingly locking bolts 2l and 22 to unlocked positions, accidentally, as, for instance, by means of a torce applied to one locking bolt at the point indicated by the arrow A in Fig. l.

Having thus described the invention, what is claimed is l. .ln a device of the class described, a pair of keepers; oppositely extended locking bolts slidable in the keepers and having rigid inner ends provided with co-ncavities in their opposite edges; a lever; a primary pivot element engaging the intermediate portion of the lever; secondary pivot elements connecting the rigid ends of the bolts with vthe lever upon opposite sides of the primary Copies of this patent may be obtained for five cents each, by addressing pivot element line parallel to and upon opposite sides of a the bolts and the primary pivot element; the lever adjacent its ends passing through and studs upon and independent ot the secondary pivot elements, the studs being engaged in the concavit'ies of the rigid ends of the bolts upon opposite sides of said positions,

of keepers bolts slidable the lever to locked constituting means be swung.

class described, a pair locking a primary pivot element secondary pivot elethe primary upon one end of the lever and independent or the secondary pivot element, the stud engaging the rigid end of one bolt to one side of a line parallel to the bolts and passing through the primary pivot element when the bolts are advanced into locked positions.

3. In a device of the class described, a keeper; a locking bolt slidable in the keeper and having a concavity in one edge; a lever; a fulcrum for the lever; a projection on the lever, engaged ing bolt; and a in the concavity of the lockpivot element connecting the locking bolt with the lever, intermediate the projection and the fulcrum of the lever.

In testimony that l claim, as administrator ot the estate of CHARLES C. McCoLLY (deceased), the foregoing as my own, I have hereto aiiixed my signature in the presence of two witnesses.
